$ patch -p1 < qmail-scanner-{version}-avg.patch
command, and follow the installation instructions as described in chapter
4.3 Third
Party Products/Qmail-Scanner.
4.2. AMaViS
You can download the package from the
http://www.amavis.org/download/ page.
Four separate packages are available:
z amavis for low and medium mail volume (home or small office use with up to
ten accounts)
z amavisd for higher mail volume
z amavisd-new for higher mail volume with various add-ons included (such as
anti-spam or ISP features)
Note: We strongly recommend the amavisd-new variant to be used with
AVG for Linux E-mail Server!
z amavis-ng, a modular rewrite of amavis (intended for experienced
administrators and/or
AMaViS developers); this project is not being
developed any longer, although its source code can be obtained via the
AMaViS CVS repository.

Prerequisites
The C language compiler and also the
make and autconf / automake
utilities are needed to build the AMaViS tools.
The essential modules responsible for extracting e-mail content and passing it
to the
AVG for Linux E-mail Server scanning engine are implemented in
Perl. This is why the Perl language interpreter has to be installed on your
system. The following Perl modules are required:
o Archive::Tar (Archive-Tar-x.xx)
o Archive::Zip (Archive-Zip-x.xx, version 1.09 or later is recommended!)
o Compress::Zlib (Compress-Zlib-x.xx)
o Convert::TNEF (Convert-TNEF-x.xx)
o Convert::UUlib (Convert-UUlib-x.xxx, stick to the newest version)
o MIME::Base64 (MIME-Base64-x.xx)
o MIME::Parser (MIME-Tools-x.xxxx)
o Mail::Internet (MailTools-1.58 or later have workarounds for Perl 5.8.0
bugs)
o Net::Server (Net-Server-x.xx)
o Net::SMTP (libnet-x.xx, use libnet-1.16 or later for better
performance)
o Digest::MD5 (Digest-MD5-x.xx)
o IO::Stringy (IO-stringy-x.xxx)
